Definitions

  • the present invention relates generally to cylindrical resonators and, more particularly, to coupling mechanisms for TE 01 ⁇ and TE 011 , mode resonators.
  • each of the resonators has a slot in the longitudinal direction that exposes the internal cavity of the resonator to an external environment.
  • the resonators are positioned in close proximity to each other with the slots aligned to couple magnetic fields within the resonators, thereby facilitating communication of the electromagnetic energy between the resonators.
  • the resonators are connected by a conductive filament.
  • the end portions of the filament form probes that extend into the inner cavities of the resonators.
  • the electromagnetic field in one resonator creates a current in the filament which, in turn, creates an electromagnetic field in the other resonator.
  • the coupling mechanism cannot be adjusted after assembly is complete.
  • the electromagnetic field created in the second resonator may be out of phase with the electromagnetic field in the first resonator by a give n amount which is determined by the characteristics of the coupling mechanism. This phase difference is constant regardless of the magnitude of the electromagnetic field in the first resonator. Additionally, the magnitude of the electromagnetic field in the second resonator is varied only by varying the magnitude of the electromagnetic field in the first resonator. In this way, the operation of the coupled resonators is set when the resonators are coupled together.
  • the present invention is directed to an improved coupling mechanism for coupling a first electromagnetic field in a first resonator to a second electromagnetic field in a second resonator, and thereby creating an electromagnetic connection to pass electromagnetic energy from the first resonator to the second resonator.
  • the coupling mechanism comprises an adjustable coupler having a first end coupled to the first resonator and a second end coupled to the second resonator.
  • the adjustable coupler is adapted to maintain the electromagnetic connection as the adjustable coupler moves between a first position and a second position.
  • the adjustable coupler When the adjustable coupler is in the first position, the electromagnetic energy passed through the coupler has a first magnitude and a first phase.
  • the adjustable coupler is in the second position, the electromagnetic energy has a second magnitude and a second phase.
  • the first and second resonators are cavity resonators each having a longitudinal axis, an internal cavity, and an exterior slot proximate one of the first and second ends of the adjustable coupler.
  • the adjustable coupler is adapted to move between the first and second positions in a direction parallel to the longitudinal axes of the resonators. When the adjustable coupler is set in the desired position, a fastening member retentively holds the adjustable coupler in place.
  • the adjustable coupler includes a support member extending between the first and second ends of the adjustable coupler, with a conductive filament passing through the length of the support member.
  • the filament extends beyond the first and second ends of the support member to form first and second probes in the cavities of the first and second resonators, respectively.
  • the first and second resonators may have exterior slots as described above, with the support member and filament adapted to slide within the slots between the first and second positions. Once in the desired position, a fastening member retentively holds the support member in place.
  • the support member and filament are rotatable about an axis defined by the first and second ends of the adjustable coupler, and the adjustable coupler moves between the first and second position by rotating about the axis.
  • the support member and filament could, alternatively, rotate about an axis parallel to the longitudinal axes of the resonators.
  • the first and second probes each have a non-linear shape so that the orientation of the probes with respect to the electromagnetic fields changes as the adjustable coupler is rotated between the first and second positions.
  • adjustment members such as dielectric screws, are inserted through the exterior surfaces of the resonators so that they abut the probes.
  • the adjustment members are adapted to cause the deflection of the probes between the first and second positions.
  • a coupling mechanism in yet another embodiment of the present invention, includes first and second resonators coupled to a waveguide.
  • the waveguide has first and second ends with an outer wall between the ends.
  • the first resonator has a first slot and is coupled to the outer wall at first aperture in the outer wall
  • the second resonator has a second slot and is coupled to the outer wall at a second aperture in the outer wall.
  • the first and second slots are separated by a longitudinal distance equal to one-half the wavelength of the electromagnetic energy, thereby providing negative relative coupling.
  • the apertures and, consequently, the resonators are equidistant from the first end in the longitudinal direction, either on the outer wall or on the second end.
  • the resonators are equidistant from the first end of the waveguide and electromagnetic energy either received or transmitted by the resonators are in phase. Consequently, this arrangement provides positive relative coupling of the resonators.
